I have a csv sitting in an S3 Bucket about 900,000 rows long, and within that csv I have two columns phone and ttl.

I am able to successfully import this csv into a new DynamoDB table, however I am NOT able to classify what type of object each column should be (which in the case of the ttl column that is classified as a string rather than number).

In the csv file itself the ttl values are not surrounded by quotation marks–just purely a number that’s being misinterpreted.
